To (IN /l.7/,()'I)I/ it may concern:

Be it known that l, TGNACY Wnontnwsm, a subject of the Emperor of Austria, and a resident of 'Krakow, Province of Galicia, Austria-Hungary, have invented certain new and useful Improvements in Casementlv'indoes, of which the following a spccilication, accompanied bydrawings.

This invention relates to improvements in French or casement windows, more particularly to that class of windows which open inwardly and in which the sashes are pivotall r and vertically movable.

The objects ol the invention are to improve upon the construction and operation of such windows and enable the sashes to he more'readily raised and lowered and maintained in anydesired position.

Further objects of the invention will hereinafter appear and to these ends the invention consists of means for carrying out the above objects embodying the features of construction, combinations of elements and ar rangement of parts having the general mode of operation substantially hereinafter I fully described and ciaimcd. in this specifics tion and shown in the accompanying draw-- ings, in which,

Figure 1 is a side elevation of a window embodying the invention; Fig. 2 is an en larged transverse sectional detail plan view, talgen through. the meeting rails of the window sashes on. the line' 2---2 of Fi 1 looking" t, Z: i

in the direction of the arrows; Fig. 3 is an enlarged detail sectional plan view on the line 3-3 of Fig. 1, looking in thedirection oi the arrows; Fig. 4 is an enlarged detail vertical ectional new on the line 4-4 of Fig: 1, looking in the direction of the arrows; Fig. 5 is an enlarged detail vertical sectional view on'the'line 5'-.5 of Fig. 1, looking in the direction of the arrows; Fig. 6 is an enlarged detail transverse vertical sectional View on the line 6-.6 of Fig. 1, iooking' in the dire'w tion of the arrows; Fig. '2' is an enl god tail side elevation ofone of the lifting tie-- vices with the casing removed; Fig. 8 is an enlarged detail frontf'; view of one of the hinges; Fi '9 is a detail front view of the hinge part y in section; FigzflO is a transverse and view of one of the raising and lowering devices.

I Referring to the drawings, A represents the window sill and B the top rail of the window frame, while C represents the side rails of the window frame. The window sashes are pivframe, and in this instance a double applicable to single windmrs or doors. The side rails D oi the window sashes are suitably pivoted to the vframe C, in this-instance frame being pro vidcd with sockets E, while the side rails ol the window sashes are pro vided with projecting hooks or pivot pins F, which sent in the sockets E and are vertically movable therein. Prefcrablytlm apertures in the sockets E slant inwardlyand the pivots F slant inwardly, so that when one ol the sashes is raised the side rail 1) is. moved away from the frame C, and the pivot pin F takes the position shown in Fig. 9 of the drawings. As the sash is lowered the pivot oin takes the position shown in Fig. 8, therey drawing the sash tightly against the frame of the window.

interlocking dust, air and waterproof connections are provided p"eferahl v on all sides of the window between the sash and the frame. shown, the window sill A is grooved along;- its icngth at-(i, and. the lower sash rail is also grooved at i. The tongue or projection J on the lower sash rail enters the groove G in the window sill when the sash is in lowered position, and the outer tongue or projection ii of the lower sash. rail is seated outside of and below the upper and outer edge of the window sill, as shown in sectional "win Fig. 4. when the sash is in lowered polon. iheierahly the grooves (l and I are htly deeper than the tongues which coi therewith, so that air spaces are left on the tongues and the bottm'ns of the grooves. According to the construction described a secure air and water tight joint is formed. The top sash rail L adapted to slide vertically inside of the upper rail B of the window frame, and su'llicicnt spa co is protilled between {T16 top of the sash rail 11 and the rail B to pe mit vertical movmncnt.

in order to open. the windmw one wing or sash is lifted sol'licicntly on its hi -gos without disconnection thereof to unlock it lrom the other wing or sash and from the casing, and then swung horizontally on its pivots. The other win or sash is likewise unlocked by a lift and then swung open. The sashes are closed in the reverse order and lowered into locked position. after being swung shut.

.hjleans are provided for thus raising; the window sashes to unlock and lock them,

which means are simple in construction, safe the window is shown, although the invention is equally in operation, compact in structure and syn1- j turned hoblr b which hook is secured to the metrical insppearance. The lifting and lowering mechanism herein shown comprises small. bracketor box 0 secured to the inner face of the window casing and a plate or bracket W secured to the inner face of the seslnn The sash bracket W is provided with tWO elongated lugs 'W? and. "NF, forming a forked projection at right angles to the plane of the sash. A lever it having a central slot R is pivoted at one end within the box. on a v stud S and provided at the other end with a pro ecting tongue which engages the forked 'projection of' the sash plate W'at the v which may have an align. r or other 1 in a plane parallel with the plane 0' lifting and lowering the sash, line c -may serve the purpose for any two or more swing said lever upward to lift and diseng outer ends of the elongated'lugs W and W.

The elongation of the lugs enables the sash to swing toward or around the end of said tong Lie without interference therewith. The tongue R is rounded as shown inFifg. 7 and there by forms in its diilerent positions a close connection with the sides of the fork avoidin lo t motionand providing a compact oonst tion. A shaft? angles to the window ijournaled in the hon r -'ne. Th s provided w; thin the box with a com or eccentrio P which engages the slot of the lever for llftll'lgG-i lowering the sash. it l connection with the shal l. serves to ti said shaft a half rotation .11 one direction to the sash and a half rotation in the opposite direction to swing sail lever downward to lower and loolrthe sash.

dow frame and may be readily applied for rank bearings of the lifting devices. in this construction the lifting mechanism is very cornpact and serves to hold the window sash when being raised or lowered, preventing sudden jars in the lowering thereof which would tend to'breali the glass. j

The side rails D of the window sashesinterlock with the side rails C of fthe framev as shown in Fig. 3fby tongue-and groove connections, and the meeting rai s Y of the sashes overlap as shown in 2 to form aweather ti ht connection. ireferahly spaces; 0 are left between the meeting faces of the sash rails Y to permit side movement of the sashes.

Means are provided for drawing the win- 'tly against the'frame when the window is clo d. the 11 per railL of o e' of the sashes is hollowe at a for ther, ception of an upwardly is provided with a vertical front face 11 and an inner face z. which slants toward the upper rail 3 the window frame so that when the In this instance window sashis closed and lowered, bringing the aperture in the plate 0 over the hook d,

the sash'isdrawn against the Window frame and tightly held in position. When the sash is raised the plate 0 is released from engagement with the hook (Z to permitthe win- (low to he '"pcned.

Preferably interlocking connections are provided between the meeting rails of the window sashes to hold said rails together when the w" 'idow is closed. As shown, the ineetin .es of the rails Y suitably rehooksfand dow is closed otion disclosed, n drop sudhut a conant oht nod in both 1 w' idow and the ry desireail pomaintained in also be seen that the raising and dev'ees siti' i 'ated conveniently n side ofthe window, and the handles nd substantially paral ith th Side of the frame when in. r e or lowered es" es will interfere with or break the ndow nes when the window is opened. Obviously some features of this invention may he 'usedwithout otlie s andthe invention may be embodied in widely varying forms. I

'll'ierefore, without limiting the invention to h the devices shown and described, and without enumerating equivalents, l claim and desire to obtain by Letters Patent the following: I 1. In .a casement window the combination of a window frame, a vertically movable window sash hingerhto swing on said frame, and
